Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled plate cooling, in particular to a wire-winding cooling device for continuous rolling of ultra-thin strips. Background Art

[0002] 1.0mm ultra-thin hot-rolled coil can not only reduce the number of cold rolling passes when used as cold-rolled raw materials, reduce production costs and save energy, but more importantly, hot-rolled ultra-thin strip steel is a unique product that truly achieves tropical cooling. It can be widely used in high-end pipe making, electromechanical equipment casing linings and other fields, with high added value and broad market prospects.

[0003] When a traditional ultra-thin hot-rolled plate device cools the produced strip steel, a large amount of coolant remains on the surface of the hot-rolled plate, causing waste, and the metal debris attached to the hot-rolled plate cannot be effectively collected, which will affect the subsequent use of the hot-rolled plate. Therefore, a wire-winding cooling device for ultra-thin strip continuous rolling is provided. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a winding cooling device for continuous rolling of ultra-thin strips. Through the coordinated use of a cooling component, a limit component, a second support roller, a first blowing component and a second blowing component, the hot-rolled plate can be cooled and the coolant can be recovered at the same time, thereby avoiding the waste of coolant to a large extent. The metal debris removed from the hot-rolled plate can be collected by the set collecting component to avoid affecting the subsequent use of the hot-rolled plate, thereby overcoming the deficiencies in the prior art and effectively solving the problem that when the existing ultra-thin hot-rolled plate device cools the produced strip, a large amount of coolant remains on the surface of the hot-rolled plate, causing waste, and the metal debris attached to the hot-rolled plate cannot be effectively collected, thereby affecting the subsequent use of the hot-rolled plate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A wire winding cooling device for continuous rolling of ultra-thin strips comprises a cooling box, a partition is fixed on one side of the inner wall of the cooling box, a filter is fixed on the bottom of the partition, a cooling assembly is provided on the top of the cooling box, a first supporting roller is rotatably mounted on the top of the cooling box located on one side of the cooling assembly, a limiting assembly is installed on the other side of the cooling assembly on the top of the cooling box, a U-shaped frame is installed on the top of the cooling box located on one side of the limiting assembly, a second supporting roller is rotatably mounted between the tops of both sides of the U-shaped frame, a first blowing assembly is installed on the upper end of the U-shaped frame, a second blowing assembly is installed on the top side of the cooling box, a collecting assembly is arranged on the bottom of the cooling box, and legs are fixed on both sides of the lower end surface of the cooling box.

[0016] 2. The coolant sprayed from the spray head not only cools the hot-rolled plate, but also flushes the metal debris attached to the hot-rolled plate into the cooling box. The adsorption effect of the electromagnet can make the washed metal debris enter the conical bucket, so as to remove and collect the metal debris from the hot-rolled plate to avoid affecting the subsequent use of the hot-rolled plate.

[0025] The cooling assembly includes a U-shaped tube 14 fixed to the top of the middle part of the cooling box 1, and the upper and lower horizontal sections of the U-shaped tube 14 are evenly spaced with spray heads 15. A pump body 11 is installed on the outer wall of one side of the cooling box 1, and one end of a liquid extraction pipe 13 connected to the liquid extraction end of the pump body 11 is connected to the side of the cooling box 1, and one end of a liquid outlet pipe 12 connected to the liquid outlet end of the pump body 11 is connected to the middle of the vertical section of the U-shaped tube 14;

[0026] The coolant in the cooling box 1 is pumped by the pump body 11 so that the coolant is sprayed out from the spray head 15 of the U-shaped tube 14;

[0027] The limiting assembly includes two end plates fixed on both sides of the top of the cooling box 1, a first limiting roller 16 is installed between the two end plates, and a second limiting roller 19 is rotatably installed between the tops of the inner walls on the opposite sides of the cooling box 1, and the first limiting roller 16 and the second limiting roller 19 are distributed up and down;

[0028] The hot rolled plate is passed between the first limiting roller 16 and the second limiting roller 19 to limit the hot rolled plate.

[0029] A first blowing assembly is installed at the upper end of the U-shaped frame 5, and the first blowing assembly includes a horizontal plate 6 fixed to the upper end surface of the U-shaped frame 5, and a first fan 7 is installed on the horizontal plate 6;

[0030] The first fan 7 is used to blow air to the upper surface of the hot-rolled plate, so that the coolant on the upper surface of the hot-rolled plate flows into the cooling box 1;

[0031] A second blowing assembly is installed on the top side of the cooling box 1, and the second blowing assembly includes a vertical plate 4 fixed on the top side of the cooling box 1, and a second fan 3 is installed on the vertical plate 4;

[0032] The second fan 3 is used to blow air to the lower surface of the hot-rolled plate, so that the coolant on the lower surface of the hot-rolled plate flows into the cooling box 1;

The stage where the hot rolled plate moves from between the first limit roller 16 and the second limit roller 19 to the second support roller 8 is inclined, and the first fan 7 is used to adjust the hot rolled plate to the upper surface. The upper surface of the hot-rolled plate is blown with air, so that the coolant on the upper surface of the hot-rolled plate flows into the cooling box 1, and the second fan 3 is used to blow air to the lower surface of the hot-rolled plate, so that the coolant on the lower surface of the hot-rolled plate flows into the cooling box 1, thereby realizing the recovery of the coolant and avoiding the waste of the coolant to a large extent. The coolant sprayed from the spray head 15 not only cools the hot-rolled plate, but also flushes the metal debris attached to the hot-rolled plate into the cooling box 1. The adsorption effect of the electromagnet 21 can make the flushed metal debris enter the conical bucket 9, so that the metal debris is removed and collected from the hot-rolled plate, avoiding affecting the subsequent use of the hot-rolled plate.
